Benefits of technology

Accordingly, it is an object of the present invention to provide a disposable cup lid which, contrary to the prior art permits easy retention of the foldback flap by engaging the tear tab in an indentation therefor, whereby the tear tab is retained in a position below the principal plane of the central region of the cup lid.

Problems solved by technology

This, however, leaves the rim of the cup lid extending upwardly into the air where it may interfere with the nose of the user.
This, however, leaves the grasp tab of the lid exposed above the plane of the cup lid.

Embodiment Construction

:

Referring first to FIG. 1, a perspective view of a preferred embodiment of the disposable cup lid of the present invention is shown. As noted above, FIGS. 2 and 4 provide cross-sections of a slightly different embodiment, which differs only in the configuration of the indentation, as described hereafter.

The cup lid 10 is, of course, intended to be placed over the open upper end of a drinking cup. Typically, such a drinking cup may be made from plastic or other coated paper, polystyrene, styrene, or otherwise; and, in any event, the drinking cup will have a substantially circular cup rim which lies substantially in a single plane. The disposable cup lid 10 is thermoformed from an extruded plastic sheet material, which has a linear extrusion grain indicated by the double-headed arrow 12.

There is a substantially planar top surface 14 which is formed in a first region of the cup lid, which first region extends on both sides of a center line 15. The center line 15 is disposed substantia...

Abstract

A disposable cup lid for placement onto a drinking cup is provided, having a tear tab which is generally aligned with the orientation of the extruded plastic sheet material from which the cup lid is made. There is a first, generally centrally located region in the lid, which has a higher elevation than the cup rim receiving recess at the periphery of the lid; and there is an indentation formed in the central region which is provided so as to accommodate the tear tab when it is folded back around a U-shaped hinge to create a drink-through opening in the cup lid. The indentation has a pair of detents located at its edges so as to hold and retain the tear tab in place when the foldback flap is folded back about the U-shaped hinge and the tear tab is inserted into the indentation. The tear tab is retained below the plane of the central region of the cup lid.

Description

This invention relates to disposable lids for placement on drinking cups; and more particularly the present invention is directed to a disposable cup lid which has a drink-through opening therein and which is such that when the foldback flap defining the drink-through opening is in its folded-back position, the tear tab which is used to initiate tearing of the cup lid so as to form the foldback flap and drink-through opening will be retained in an indentation formed in the cup lid below the plane of the central region thereof. Accordingly, lids which are in keeping with the present invention have the advantage that the tear tab is retained in place when the foldback flap is in its folded-back position, and therefore the tear tab does not interfere particularly with the nose of a person drinking from the cup on which the cup lid of the present invention has been placed.Disposable cup lids having drink-through openings are very well known. The advantage of a drink-through opening is t...
